Irises: blue and green

I like this shot, despite its compositional flaws. What're those flower fragments doing at the top? Of course, I knew they'd be there when I framed the shot, but I didn't care. And those buds. Nor are the two main flowers centered top-to-bottom. 

What I mainly like is the color contrast: Blue against green. The green isn't flat, of course. These aren't flowers posed in a studio. They're flowers I flicked in the wild. Well, not exactly wild, as they're in a garden in an island on 11th Street in Hoboken, NJ. So once can seem to articulation, some structure, in the green.

The flowers are in focus, hence sharp. The background is not, hence blurred.
